Heredity (Edinb) 97:119-26. 2006..Overall, this study shows apomixis can be partial, and provides evidence for higher levels of inbreeding in polyploids compared to diploids and for significant levels of apomixis in a diploid plant population... - Inbreeding in Japanese quail estimated by pedigree and microsatellite analysesShin Hun Kim
